The Marriott Center is a 20,951-seat multi-purpose arena on the campus of Brigham Young University in Provo, Utah. It is home to the BYU Cougars men's and women's basketball teams. It is among the largest on-campus basketball arenas in the United States. It is also the largest basketball arena in the West Coast Conference, in which BYU competes for most sports except football. In addition to basketball, the Marriott Center is used for weekly devotionals and forums.
The Marriott Center was named in honor of benefactor and hotel magnate J. Willard Marriott, founder of the Marriott Corporation. When the arena opened in 1971, it replaced the University of Minnesota's Williams Arena as the largest college basketball arena in the United States. It was also the largest venue in the nation built for basketball, being larger than any NBA arena at that time. It would lose both distinctions when the University of Kentucky men's basketball team moved into Rupp Arena in 1976, but would remain the nation's largest basketball-specific facility on a college campus until 1987, when the University of Tennessee opened Thompson-Boling Arena. In April 2012, BYU announced renovations to the Marriott Center. The lower bench seating on the north side was replaced with prime chair seating. A new sound system was installed, the men's and women's locker rooms were renovated. The changes in the lower seating lowered the Marriott Center’s capacity from 22,700 to 20,951. 
Previously, the Cougars basketball team played at the Smith Fieldhouse. The court was replaced in 2003 with a permanent floor.
The facility hosted the 1988 Western Athletic Conference men's basketball tournament. It also hosted the West Regionals of the NCAA Men's Division I Basketball Championship in 1972, 1977, 1979 and 1982.
On February 19, 1999, the Marriott Center set an NCAA record for highest attendance for a men's volleyball match: 14,156 fans watched BYU defeat the University of Hawaii, shattering the previous record of 10,225 (held by Hawaii).
